With setting 1, the settable ISO speed range will be 200 - 1600.
Also, the ISO speed displayed in the viewfinder, will have the “0” displayed
as a smaller character such as “2oo”. When the image’s shooting
information (p.131) is displayed, the ISO speed’s “0” will also be displayed
as a smaller character.
